Remote Control FOV Helper
Advanced AutonomyIntermediate Robotics plus perception pipelines, control loops, coordinate frames, and real-time behavior.
Before you start
- Complete Camera Module and Web Remote Controller
- Understand depth regions, coordinate frames, and browser overlays
- Instructor approval for any controller or deployment change
Build a read-only camera overlay that helps an operator understand visible space, blind spots, and nearby obstacles during teleoperation.
Project Outcome
Show left, center, and right hazard bars plus the camera's usable field-of-view boundary. The first version runs separately from the deployed controller.
Camera Input
- Depth map and camera image
- Camera field-of-view limits
- Configured left, center, and right regions
Build Stages
- Divide the image and depth map into three regions.
- Calculate a robust near-obstacle distance for each region.
- Map distance to clear, warning, and hazard labels.
- Draw field-of-view and region overlays on the image.
- Test the display with known obstacle positions.
- Present the read-only prototype for review before any controller integration.
First Prototype
Display three hazard bars beside a local camera view and update them from live depth data.
What To Measure
- Whether displayed regions match the physical scene
- Alert stability near zone boundaries
- Camera latency and display refresh rate
- Obstacles missed outside the camera field of view
Extensions
- Add an edge-of-frame warning.
- Show nearest distance for each region.
- Add a top-down occupancy sketch.
- Integrate the reviewed overlay into an approved web controller deployment.
Safety Boundary
The overlay provides awareness only. It cannot see outside the camera field of view and must not replace direct observation, physical E-stop access, or controller safety checks.
